Euphorbia Preslii, Guss., (spurge) and Euphorbia maculata, L. 
(spotted spurge). It will be seen that this is a variable set, vary- 
ing in size from the charlock and its cousin the wild radish down 
to the prostrate carpet weed and spotted spurge. All form seed 
in great abundance, the ketmia in large capsules, the sow thistle 
in heads and provided with airy balloons, but most of the species 
have inconspicuous seed vessels. 
In the group of perennials with medium sized fascicled roots, 
there are four species to mention, namely: Ranunculus acris, L. 
(tall buttercup), Hzeracium aurantiacum, L. (orange hawkweed), 
Rudbeckia hirta, L. (cone-flower) and Cyperus rotundus, L. (coco- 
grass). The buttercup is an old weed of the grass land, while 
the hawkweed is a comparatively new comer and is spreading 
rapidly. In the cone-flower we have a prairie weed that has 
spread eastward rapidly and vies with the common daisy for the 
occupation of the meadows. In the coco or nut-grass there is 4 
very difficult pest to eradicate on account of its ‘‘ nuts” below 
ground, which serve to spread the weed. There is but a single 
biennial to be mentioned here, but it is a very common one—the 
Erigeron Canadensis, L. (fleabane or horseweed). The annuals 
again are the largest in number, there being six as follows: A” 
themis arvensis, L. (chamomile), Erechthites hieracifolia, (L.) Rat 
(fireweed), Polygonum Pennsylvanicum, L. (smartweed), Bromus 
secalinus, L. (cheat or chess), Panicum Crus-galli, L., (barnyard 
grass), Panicum sanguinale, \.. (crab or finger grass). The chess 
has the greatest variety as a weed; the fireweed is the rankest 
grower in places suited for it and the two Panicums are almost 
everywhere. 
In the group with the root somewhat below the average i? 
size, there are for the tap-rooted sorts only one for the biennials, 
namely : Lamium amplexicaule, L. (dead-nettle), and two for the 
annuals, as follows: Svellaria media, (L.), Smith (chickweed), 
Portulaca oleracea, L. (purslane). These are all small plants, the 
dead-nettle or henbit reaching highest from the ground, while 
the purslane is a succulent prostrate weed. 
In the fascicled group for the size called number four there 
are two species, namely: Ranunculus bulbosus, L. (butter 
cup) and Chrysanthemum Leucanthemum, L. (ox-eye daisy).
